Alright guys, thanks for the inputs, I've tried the guitar out and I really can't hear that anything is wrong. I'm having second thoughts about the pickup itself though, so I think I'll send Tim another email.
In short, I like how thick it is, and I like it's cleans, but I'd like some more chug. AV Warpig? And how long after I recevied the pickup can I send it back? Maybe I'm better of trying to sell it and buy a brand new one?
Oh, nevermind, the absence of chug was mostly because of my still quite poor palmmute technique with the Edge bridge, lol.
I'll keep this pickup for now, it sounds great. :)
WFD: No man, it came like this from the factory as far as I know, the finish is called TKS if I remember correctly, Transparent Black "Something"? (not satin, cause it's really gloss as you can see). It's more or less natural with a slight black burst and natural binding.
